DOORKNOB COVER.

Application filed March 23, 1926. Serial No. 96,746.

This invention relates to door knob covers and more particularly to adevice for covering the ordinary door knob applicable to the door knobwhile the same is in its usual position and providing the knob with asurfacesuch that the knob is fully cushioned to prevent damage therebyto objects with which it may come into contact when the door is swung inthe open position.

A further and more specific object of the invention is to provide aresilient cover engaging and by its own resiliency closely fitt ng thedoor knob, this cover at once providing a cushion for protecting objectsagainst damage by the knob and a means for grasping the knob to turn thesame when the hands are Wet and slippery.

These and other objects we attain by the construction shown in theaccompanying drawing, wherein for the purpose of illustration isshown apreferred embodiment of our invention and wherein:

Figure 1 is a side elevation of a door knob having a cover constructedin accordance with our invention applied thereto;

Figure 2 is a front elevation thereof;

Figure 3 is a sectional view taken through the cover while in positionupon the knob;

Figure 4 is a section through the cover taken on the line 4-4 of Figure3.

Referrin now more particularly to the drawing. the numeral 10 indicatesa door knob and 11 a covering therefor preferably formed of live rubberof substantially the same contour as the door knob to which it is to beapplied. At present, a circular knob has been illustrated, but it will,of course, be understood that the cover may be modified to adapt it tooval, square or other types of knobs. The cover is substantially in theform of a cup, the bottom wall 12 of which engages the outer surface ofthe knob when the cover is in applied position. The mouth 13 of this cupis of less size than the greatest diameter of the knob so that the covermust be sprung into place thereon and will not slip or fall therefrom.The bottom wall 12 hereinbefore referred to may be, if so desired,provided with corrugations 14 which may be arranged upon either theinner or outer surface of the cover. ()n the present illustration, theseare shown as arranged upon both surfaces of the cover, those upon theinner surface serving to prevent slipping of the covering upon the knobwhile those upon the exterior serve both to prevent slipping of the handupon the cover and as a means for ornamenting the cover. The interiorcorrugations also serve to increase the cushioning effect of thecovering.

Other changes being possible in the construction hereinbefore set forthwithout departing from the spirit of the invention, we do not limitourselves to such specific structure except as hereinafter claimed.

We claim 1. As an improved article of manufacture, a cover for a doorknob comprising a cupshaped elementof resilient material ofsubstantially the same contour as the door knob to which it is to beapplied, said element having a mouth of less size than the greatestdiameter of the knob, the wall of the cup for contact with the face ofthe knob being interiorly corrugated to increase the cushioning effect.f 2. As an improved article of manufacture, a cover for a door knoocomprising a cupshaped element of resilient material ofsubstantially thesame contour as the door knob to which it is to be applied, said elementhaving a mouth of less size than the greatest diameter of the knob, thewall of the cup for contact with the face of the knob being interiorlycorrugated to increase the cushioning efiect,and the outer surface beingalso corrugated to afford a better grip to prevent slipping of the handupon the cup.

In testimony whereof we hereunto affix our signatures.
